Application filed May 15, 1925, Serial No.

In looms for weaving tufted pile fabrics in which grippers or devices are provided for draw elf portions of tuft yarn from spools, and, after the portions drawn off are severed from the yarns on the spools, inserting them between warp threads, use has been made or proposed of transferring mechanisms which i disengage tube frames holding spools and placed two or more in line end to end to present practically continuous lines of spools and tubes from carrying chains and move them in line into a position in which they present tuft yarn to the grippers or devices for drawing off portions to be severed and after the severance thereof move the tube frames from that position back again into engagen'ient with the carrying chains while the grippers insert the severed portions of tuft yarn between warp threads.

This invention of improvements in looms for weaving tufted pile fabrics relates to the mechanism for disengaging and removing tube frames with guide tubes for the tuft yarn and spools of tuft yarn from the carrying chains used to convey the tube frames and spools of tuft yarn in due order to and from places at which they are required to be used for the supply of the tuft yarn for insertion between warp threads, for causing the tube frames to insert tuft yarn l etween warp threads and afterwards for restoring the tube frames to the carrying chains.

The invention consists in mechanism for disengaging and removing the tube frames from the carrying chains and causing them to insert tuft yarn between warp threads which, retaining the advantage hitherto obtained only in looms in which tube frames are used sing y, that the tube frames after removal from the carrying chains are them selves made to insert tuft yarn between warp threads, to draw off tuft yarn from the spools. to be withdrawn to a position at a predetermined distance from the warp threads in order to leave tuft yarn between the warp threads and to draw off tuft yarn from the spools, and to remain in that position in order to hold taut the portions drawn oil' until after the severance of the portions of tuft yarn between warp threads from the yarn on the spools, and are then restored to the carrving chains, presents in comparison with mechanism hitherto provided for the like pin-pose, the advantages that it enables looms to be built for weaving fabrics of i of any width requisite width a no 30,643, and in Great Britain May 17, 1924.

without the use of inconveniently long and heavy tube frames and spools for holding tuft yarn and enables looms to be built of parts in sets each member of which is interchangeable with or corresponds closely to the corresponding member of another set so that any suitable number of sets or parts can be used with other necessary co-operating parts in building looms of any width desirable with any number of tube frames operated and used simultaneously and in alignment and that similar tube frames can be used in any of such looms. A further advantage afforded by the mechanism provided according to this invention for removing tube frames from carrying chains, causing the tube frames to insert tuft yarn between warp threads and afterwards restoring the tube frames to the carrying chains, is that the tube frames operated and used two or more simultaneously and in alignment are held immovably and irremovably in the parts holding and operating them and being held securely can be operated speedily.

According to this invention, holders to be hereinafter further described and illustrated by the accompanying drawings, are provided one on each side and one, two or more in a position or positions intermediate between the sides of a tufted pile fabric loom which present notches to receive hook like projections extending in the general plane of end plates of tube frames and are adapted to receive tube frames applied end to end in line and presenting practically continuous lines of spools and tubes and are oscillatably mounted upon parts provided for moving them up and down and are in connection with means for oscillating them and are provided with pressing devices oscillatably mounted upon them and in connection with means for oscillating such devices for pressing upon and releasing the tails of pivoted hooks of tube frames and releasing such tube frames from carrying chains and holding them in and releasing them from the holders, so that the holders are capable of taking tube frames in line end to end from carrying chains and, while continuing to hold them in line end to end. inserting the yarn tubes of the tube frames between the warp threads in the loom, being drawn back to leave por tions of tuft yarn between the warp threads and to cause other portions of requisite length to be drawn from the spools and out through the tubes to he l ft to 'g'iro iiide ill 'therethrough and, after portions of tuft yarn between warp threads have been severed from yarn on the spools, restoring the tube frames again to the carrying chains and making it possible to apply in the use of tube frames in line end to end the method hitherto only applied in looms in which tube frames are used singly.

Figs. 1 and 2 of the accompanying drawings show an illustrative example of the mechanism according to this invention for disengaging tube frames from the carrying chains and inserting tuft yarns between warp threads and again restoring the tube frames to the carrying chains in a loom, and other mechanism used in a loom, sufiiciently to illustrate this inventionand to make clear the manner of carrying it into effect. The framework is omitted for simplicity, and for clearness some parts shown in Fig. 2 are omitted from Fig. 1.

Fig. 1 is a side elevation partly in vertical section and Fig. 2 is a. front elevation drawn in two parts on two sheets. Fig. 3 is a front elevation and Fig. 1 a sine elevation of a tube frame of a form adapted for use with the mechanism illustrated by Figs. 1 and 2, and Fig. 5 is a plan of parts shown in Figs. 3 and 4. Fig. 6 is a front elevation and Fig. 7 a plan of a'holderat the left hand of a loom and Fig. 8 is a side elevation thereof. Fig. 9 is a front elevation and Fig. 10 is a plan of a holder intern'iediate between the sides of the loom and Fig. 11 is a side elevation thereof. Fig. 12 is a front elevation and Fig. 13 is a plan of a holder at the right hand side of the loom. Fig. 1 1 is a perspective view of a holder at the right hand side of the loom and Fig. 15 is a perspective view of a holder intermediate between the sides of the loom. The same numerals of reference indicate corresponding parts in different figures.

In the mechanism shown in Figs. 1 and 2,

1, 2 are holders of two forms for engagement with the tube frames 3 with yarn tubes land carrying spools 5, one of which tube frames 3 with its yarn tubes at and spool 5 is shown more clearly in Figs. 3 and 41-, and for rcn'ioving such tube frames 3 from the carrying chains 6 and presenting them in line end toend'and causing them to insert their tubes 41 and so tuft yarn, between warp threads and after the severance of the inserted tufts restoring the tube frames 3 to line end to end and consequently is always greater by one than the number of tube frames 3 so to be used. The warp threads and the weft are omitted from the drawing for clearness' but their position is indicated sufficiently by the healds 7, the slay 8, the reed 9, the supporting plate 10 and the knives 11, 12 which are similar and worked similarly to those used in looms of already well known construction but are made of a width corresponding to the width of the fabric to be produced in a loom. The tube frames 3 and the end plates 18 provided therein form no part of the present invention but are represented in the accompanying drawings and will be briefly described herein to facilitate description of the mechanism of the loom. The end plat-es 18 form the subject of application for United States Letters Patent No. 30,6 14 dated May 15th, 1925. Each end plate 18 is formed mainly as a plate presenting a plane outer surface directed outwardly from a spool in the tube frame on which it is provided and presents a projection 4:8 in its general plane to enter between the side plates of a link of a ca rying chain and also presents a book like projection '19 extending in its general plane downwardly and to the rear when the end plate 18 is to be disengaged from a chain 6. The projection 19 is shown as narrowing towards its end. Each end plate 18 has a book 20 capable of projection and retract-ion laterally and furnished with a projection or tail 21 extending laterally within the length of the tube frame by which the book 20 may be retracted and disengaged from the chain 6.

Each end plate 18 is formed on the site to be turned towards a spool '5 in the tube frame with projections 4 1, extending laterally for the attachment of a bar 16 furnished with yarn tubes to be at the rear and bottom when the end plate 18 is inposition for disengagement from a carrying chain 6. The holders 1, 2 are mounted by means of pivots 13, 14 respectively on arms 15, 16 of two forms carried by and movable by a shaft 17 mounted to be oscillated by meansof a cam and spring in a suitable framework, which cam and spring and framework are not shown but are similar to corresponding parts in looms already well known, into atop position for the holders 1, 2 to receive tube frames 3 from the carrying chains 6, then into a bottom position for the tuft yarns to be inserted between warp threads, then into a lower intermediate position for tuft yarn to be drawn from spools 5 in the tube frames 3 by the movement of the tube frames 3 from the lower position to that intermediate position and for the tuft yarn inserted between the warp threads to be cut off from that on the spools 5, then again to the top position to restore tube frames 3 to the carrying chains 6 and lastly into an upper intermediate position to allow the tube frames 3 released to be moved from 1 "1 r 1 above tne homers ,r, .2 others to be brought above them to be engaged thereby.

The arm for carrying a holder 1 is formed in two parts fastened together as by bolts namely a part 151 forked for the holder 1 to be mounted between the jaws forming the fork and a part 152 fast on the shaft 17.

The arms 15 at the two sides of the loom are similar but have their parts and in particular, the forked parts 151 disposed reversely as regards lateral direction so as "to be of opposite hand and apart from the formation of the forked part 151 and corresponding forked partat the other side of the loom these two arms are similar to corresponding arms employed in looms for weaving pile fabrics by means of single tube frames extending across the width of the fabrics being woven. Similarly an arm 16 intermediate between the sides of the loom is formed in two parts fastened together as by bolts namely part 161 forked to re ceive the holder 2 and a part 162 fast on the shaft 17.

The number of these arms 15, 16 with forked parts 151 and 161 provided in a loom is greater by one than the number of tube frames 3 to be taken from and restored to the carrying chains 6 at one time and consequently in any case there is one less arm 16 than there are tube frames 3 to be taken at one time. 7

Each forked part 151 supports a holder 1 and the one or each forked part 161 provided in a loom supports a holder 2. The two holders 1 are of opposite hand as indicated at the two sides of Fig. 2. There may be one holder 2 or more according as two or more tube frames 3 are to be taken from of end plates.

Each holder 2 to be applied in intermediate positions between the sides of a loom is adapted to receive two end plates 18 at a time by being provided with a notch 22 and a projection 23 of sufficient width in the direction across the loom to receive the hooks 19 and lower angles of two end plates 18 applied one against the other. The holders are each adapted to receive one end plate 18 being provided with a notch 22 to receive the hook 19 and a projection 23 to afford bearing for the lower angle of one end plate 18 and being provided with a curved orinclin'ed face 26 directed inwardly across the loom to press together the tubeframes 3 placed end to end.

To each holder 1 or 2 there is pivoted an arm 27 with two projections 28 in the case of a holder 2 in an intermediate position between the sides of a loom or with one projection 28 in the case of a holder 1 at the side of a loom to engage with the hooks or hook provided on the end plates or end plate 18 in connection with a chain 6 to which the holder 2 or 1 may be presented and thereby to disengage the hooks or h'o'ok 20 from the chain 6 and also to hold the end plates or end plate 18 firmly in the notches 22 of the holders 2 or 1, by bearing on the tails of the hooks 20' and on the upper parts of the hooks 19.

Connecting rods 29 adjustable in length and surrounding the pivots of the arms 27 connect the holders 1 and 2 to studs in the arms 30 fast on a shaft 31 mounted in bear ings in brackets 32 carried by the arms 15, 16. Astrid 33 in an arm fast on the shaft 31 is connected by a connecting rod to a stud 36 in a lever 37 mounted loose upon the shaft 17 and a connecting rod 38 moved by'a stationary cam or other device.

Studs in the arms 27 are connected by connecting rods 39 adjustable in length to studs in arms 10 fast upon a shaft ll which is also mounted in hearings in the brackets 32 and moved by means of a moving or stationary-cam or other device.

The movements to be given to the holders 1 and 2 and the arms 27 by means of the shafts 17, 31 and 41 are precisely similar to the movements given by means of corresponding shafts to the holders and tube frames releasing and gripping arms used in looms already well known for inserting tuft yarn in pile fabrics of the width corresponding to the length of a single spool of tuft yarn and consequently the movements of the shafts 17, 31 and 41 are effected by mechanism similar to that used for operating the corresponding shafts of such looms and so not needingdescription herein. The shaft 17 being moved at appropriate times in the working of the loom to raise and lower the holders 1, 2, the holders 1 2, are presented to tube plates carried by the chain 6 and lowered into position for the tubes 4 of tube frames in the holders 1, 2 to pass between warp threads and to remain in that position for a suitable time and then raised into the position in which they are indicated in Figs. 1 and 2 to withdraw the tubes 4 from between warp threads and to draw portions of tuft yarn from the spools 5 and to leave space between the tubes 1- and the warp threads for the passage of the knives 11, 12 and then after the action of the knives l1 are raised to re- Cir 1 tube frames 3 contact of the end plates 18 with the curved or inclined face 26 and the turn tube frames to the chains 6 then lowered to allow other tube frames 3 to be brought into position to be engaged by the holders 1, 2 and then raised again to engage these other tube frames3. By the movement of the connecting rods 29 connected with the holders 1 and 2 and the shaft 31 the holders 1, 2 are moved at appropriate times so that the holders 1, 2,receive tube frames 3 from the chains 6, present the tubes 4 of the tube frames 3 obliquely to and introduce them between the warp threads and turn them into position to place the tuft yarns extending through them in a vertical or approximately vertical position and after the portions of tuft yarns inserted between warp threads have been cut off from the yarn on the spools 5, the holders 1, 2 present the tube frames 3 in position to be engaged with the chains 6. By the movement of the connecting rods 39 connected with the shaft 41 and the arms 27 mounted on the holders 1, 2, the projections 28 are made to engage with the hooks 20 for disengaging them from the chains :6 and for pressing on the hooks 20 and the hooks 19 and keeping the tube frames held in the holders 1, 2 and when the holders 1, 2 present the tube frames 3 again to the chains 6 to relieve the hooks 20 from pressure so that the springs 48 vused therewith may reengage the hooks 20 with the chains 6.

WVhen the holders 1, 2 are presented to tube frames 3 on the chains 6 the downwardly projecting hooks 19 of the end frames 18 are received in the notches 22 of theholders 1, 2 and the lower angles of the end plates 18 bear on the projections 23 so that secure and precise bearing of the tube frames 3 in the holders 1, 2 is brought about and when the arms 27 are made to press on the tails 21 of the hooks 20 to disengage them from the chains 6 they will continue to press on the tails 21 and on the hooks 19 of the end plates 18 and so will hold the tube frames 3 firmly and immovably in the holders 1, 2 and against accidental'or other removal therefrom during movement from the chain 6 to the warp threads, during movement while the tubes are between warp threads, during movement into position" for tuft yarn inserted between warp threads to be drawn off from the spools, and for the portions between warp threads to be cut off from yarn on the spools-5 and during the return movement of the tube frames 3 back to the chains 6. Further when the holder 1 and the corresponding holder at the other side of theloom are presented to the end plates 18 0f corresponding face at the otherside of the loom will cause the tube frames 3 which are placed in line to be pressed together end to end in the line across the loom so that being so pressed together andheld firmly in the holders by the arms 27 the line of tube frames 3 applied end to end will act as though it were one tube frame extending from side to side of the loom. Obviously any number of parts shown as mounted upon and operated by means of the shafts 17, 31, 41 for holding and working tube frames 3 may be provided in order to provide for the holding and working of any numberof tube frames 3 endto end in line with spools 5 in them which itmay be requisite to provide for in the construction of a loom. I

The mechanism employed according to this invention may be different in detail in different cases. For example, instead of forked arms to carry the holders for tube frames, arms with pivots projecting on one side or both sides may be used and the projections or parts for engaging with the tails of the hooks on end'plates may be made to work up and down or horizontally or otherwise according to the formation and disposition of the hooks and the tube frames to :be employed may be provided with end plates of appropriate forin or construction and the holders to receive the tube frames may be formed in any way requisite to correspond with them.
